ROSE

Application February 11, 1938, Serial No. 190,112

1 Claim.

The present invention relates to a new and distinct variety of rose plant originated as the result of a definite effort to improve upon a rose, as yet an unnamed seedling, which in turn was the result of a cross between Senior (Plant Patent No. 2) as the pollen parent, and De Luxe as the seed parent.

While the flower of this unnamed seedling possessed a very desirable brilliant pink color, it had too few petals to warrant dissemination. Therefore, my primary object in view was to obtain a better petal characteristic, such as possessed by Sweet Adeline (Plant Patent No. 6) and at the same time overcome one of the undesirable characters of the last named variety. "Sweet Adeline is a very diiiicult rose to propagate by grafting on Manetti stock, for I found that even after union was made, the scions would leave the manetti with the result of loss of many plants during blooming season.

In carrying out this invention, I crossed this unnamed seedling with Sweet Adeline and obtained the present rose, which has as its outstanding characteristics (1) Distinctiveness of color and size of its blossoms;

(2) A better growing habit, greater productiveness per plant of cut flowers than its parents;

(3) An easy propagation character.

Asexual reproduction proves these characteristics to be fixed.

The original illustration shows the blossoms of this new variety in full color and substantially natural size and in four difierent stages of development from bud to full blown rose, and the following is a detailed description of the rose, color designations being in accordance with Ridgways Color Standard:-
